10.2 Cleaning
We recommend that the instrument is checked and certified by Zehntner every two
years. Clean the
aluminium housing
with a proper, soft cloth and use
commercially available cleaning agents such as cleaning agents for glass, benzene,
acetone. Furthermore, we recommend cleaning the instrument periodically using
water- and oil-free compressed air (max. 1.5 to 2 bar).
Do not use strong acids or alkaline liquids!
Unplug the measuring head from the car before cleaning.
Never immerse the device into water or other liquids.
Make sure that no cleaning liquid flows into the interior of the instrument.
The
optics window
is coated with a special antireflection coating that should not be
damaged. If the soft brush is not sufficient for cleaning the window, you may use a
soft paper tissue and window cleaner.
The instrument consists of delicate optical and electronic precision parts. Do
not drop it and protect it from shocks, moisture and dust.
Do not open the measuring head for cleaning. If you recognize dust or small
particles on the cooling air inlet and outlet, you may remove the protection grid
and clean the inside of inlet and outlet with a vacuum.
10.3 Replacing the lamp
Make sure the lamp is cold before you replace it. Please do not touch the
bulb and reflector.
